Commit 0217a272fe13 ("scsi: ibmvfc: Store return code of H_FREE_SUB_CRQ
during cleanup") wrongly changed the busy loop check to use
rtas_busy_delay() instead of H_BUSY and H_IS_LONG_BUSY(). The busy
return codes for RTAS and hypercalls are not the same.
Fix this issue by restoring the use of H_BUSY and H_IS_LONG_BUSY().
